Man they better not nerf it. It is a fun fight. Kinda sad its a one time only fight.

For tips on how to beat it... I'll assume you use a controller beings you dread the duty action button so bind that to something. Next zoom out and take note of the radius of your blast when you use the button. Then its a simple matter of playing Missile Command until the combat phase. There just stay out of the fire, and get under the shield when it pops up.
